Answer:
This line can be represented by the line y = 3/4x + 2.
Step-by-step explanation:
The slope is identified as the m in y = mx + b. The slope is the rise/run of your line (AKA how many units it goes upwards/downwards and then goes to the right/left to meet the second given point).
In this case, the line rises 3 units from 2 to 5, and then goes to the right by 4 units to meet the coordinate (4, 5).
B in the equation refers to the y-intercept, or where the line intersects/crosses the y-axis. In this case, it is the coordinate (0, 2).
Finally, x is irrelevant and is placed in the equation for no reason (at least that I am aware of in my several years of high school math).
Therefore, your final equation is y = 3/4x + 2.
Answer:
Divide £700 in the ratio 5:3:2.
The total number of 'parts' in this ratio
= 5 + 3 + 2 = 10.
So, to work out how much of the total corresponds to 1 part, we need to divide the total sum by the total number of parts: 700/10 = £70.
Now, we can multiply the amount we know for 1 part by each value in the ratio.
Step-by-step explanation:
70 × 5 = £ 350
70 × 3 = £ 210
70 × 2 = £ 140
Hello! To find out the amount of ceramic chickens he has in total, we can write and solve a proportion. Set it up like this:
11/x = 10/100
This is because 11 was just the 10% given as gifts, and we are looking for the total amount. Cross multiply the values in order to get 1,100 = 10x. Divide each side by 10 to isolate the x. 1,100/10 is 110. Let's check. 110 * 10% (0.1) = 11. There. x = 110. Cam has 110 ceramic chickens total.
